Title: Apparatus for producing preform of optical fiber
Inventor: KOIDE TOSHIO
IPC: C03B37/014
Filed: 1991-05-17
Abstract: PURPOSE:To obtain a preform of optical fiber having stabilized characteristics continuously measuring the concentration and flow rate of a raw material gas fed to a reaction system and feeding the product of the concentration and the flow rate back to the raw material feeding system. CONSTITUTION:A carrier gas (e.g. helium) is fed into a raw material vaporizer 1 composed of a saturator, etc., capable of feeding the carrier gas into a liquid raw material, producing bubbles and saturating the gas in the bubbles with the vapor of the raw material liquid to vaporize the raw material (e.g. silicon tetrachloride). The flow rate of the raw material gas fed to the reaction system is measured with a flowmeter 3 and the flow rate of the raw material gas branched with a branching device 2 is measured with a flowmeter 4. The branched raw material gas is then fed to a gas mixer 6 and mixed with a diluting gas (e.g. helium) and the flow rate is measured with a flowmeter 5. The concentration of the objective component is measured with a concentration measuring instrument 7. The concentration of the raw material gas fed to the reaction system is calculated from the aforementioned data with a controller 8 and feedback control to the vaporizer 1 is carried out so that the product of the concentration and flow rate may be constant.

Therefore, the gas in the bomb does not flow out and is kept in the bomb. When this apparatus is to be used, the lever 13b is rotated and released from the tied condition, then, the lever 13b is moved along the direction A by the spring 14 and a projection 13a pushes up a ball 9. The gas in the bomb flows out into the tin 1 through the cylinder 12, and, when the pressure in the tin 1 reaches a prescribed one, the lever 13b is moved in the direction which is opposite to the direction A, and the flowing out of the gas is stopped. When the operating section of this apparatus is depressed, the medicine contained in the tin 1 is sprayed out.

Title: Device for connecting slip ring to current guide of superconductive rotor
Inventor: ROJIE JIRE
IPC: H02K55/04
Filed: 1981-09-11
Abstract: The current lead operates at a cryogenic temperature. The collector ring operates at room temperature. While the rotor is being cooled down there is considerable relative movement between them due to thermal contraction. Electrical connection is ensured by interconnecting "rear" or cold side rods with "front" or warm side rodes. The device of the present invention comprises an insulating connector box (12) mounted on the shaft of the rotor. Inside the connector box there are inner and outer pairs of contact blocks (24,23) which clamp onto both a single rear rod (14) and a pair of front rods (16,18). The clamping force is provided by flyweights (28a,b,c). The rotor may thus be cooled to cryogenic temperatures while stationary or rotating slowly since the rods are loosely clamped if at all, and can slide relative to each other. Once working temperatures are reached the rotor is accelerated and the rods are tightly clamped to provide good electrical contact.

Title: Recorder
Inventor: MISHIMA TOSHIAKI
IPC: G01F1/36
Filed: 1992-05-11
Abstract: PURPOSE:To measure flow rate correctly by determining the flow rate according to a specific formula based on a DC voltage or DC current within a specific range which corresponds to the pressure difference across an orifice. CONSTITUTION:Flow rate is determined according to a formula based on a DC voltage of 1-5V or a DC current of 4-20mA which corresponds to the pressure difference across an orifice 2. In the formula, VX is a transmitting voltage value corresponding to a pressure difference signal, VMIN is a transmitting voltage value for a minimum detectable pressure difference signal, VMAX is a transmitting voltage value for a maximum detectable pressure difference signal, FMAX is a flow rate for maximum detectable pressure difference signal, FMIN is a flow rate for the minimum detectable pressure difference signal, and FX is a flow rate for the transmitting voltage value VX. When a range setter 1 sets DELTAPmin at 4mA and DELTAPmax at 20mA, a flow rate FX detected through the orifice 2 is delivered as a pressure device value DELTAPx to a pressure difference transmitter 3 and a current within the set range of 4-20mA is transmitted. Consequently, a pressure difference signal in the range of 1-5V appears across a resistor 4 and recorded on a recorder 5 thus realizing correct measurement of flow rate.
